HANDLE-BAR FASTVENING.

SPECIFICATION forming part of Letters Patent No. 620,848, dated March'7, 1899.

Application iiled November 7, 1898. Serial No. 695.789. (No model.)

To all whom it may concern:

v Be it known that I, ANTHONY JEROME, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain newand useful Improvements in Handle Bar Fastenings;and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specification.

rihis invention relates to that type of handle-bar fastenings forbicycles and the like in which the one operation of the mechanismperforms a dual functionto wit, securing the handle-bar proper in fixedrelation to the handle-bar stem and the handle-bar stem in fixedrelation to the steering-stern or arbor of the bicycle. V

The object of the present improvement is to provide a simple, durable,and effective combination and arrangement of parts by which theabove-mentioned dual fastening of `the parts is attained in a ready andsubstantial manner, as will hereinafter more fully appear, and be moreparticularly pointed out vin the claims. l attain such objects by theconstruction and arrangement of parts illustrated in the accompanyingdrawings, in which- Figure l is an enlarged detail central sectionalelevation of a bicycle-handle and connections, illustrating the presentinvention; Fig. 2, an enlarged detail side elevation of the duplexexpanding stem and its operating mechanism; Fig. 3, an enlarged detailhorizontal section of the same at line @c fc.

Similar numerals of reference indicate like parts in the differentviews.

Referring to the drawings, l represents the handle-'bar proper, providedwith a Central head 2, through which is formed a central vertical borethat iits upon the outer and upper end of the handle-bar stem 3 in aremovable manner, so that such handle-bar may be capable of removal andreversal, as required. In the present improvement the handle-bar stem 3is separate from the handle-bar proper, and its upper and lower ends areof a longitndinally-slitted nature, as shown, and each end is formedwith a tapering counterbore 4 and 5, which counterborestaper or flareont- 5o wardly and in opposite directions, as shown.4

6 and 7 are eXteriorly-tapering nuts or expanders fitting thecounterbores 4 and '5 of the handle-bar stem, and the nut 6 is heldagainst independent rotation by individual studs 8 on 55 said nut orplug engaging in the longitudinal slits in the stem, as shown.

9 is the operating-bolt of the present mechanism, formed with`screw-threaded portions 10 and ll, thathave engagement in axially- 6oscrew-threaded orifices in the respective nuts or expanders 6 and 7,said screw-threads being of a right and left hand nature, respectively,or other vequivalent differential nature, so that the rotation of thebolt 9 will 65 move said nuts or expanders 6 and 7 longitudinally inopposite directions. At its upper end the bolt 9 is formed with aprojecting angular head l2 for con veniencein operatin g the same.

14 is a collar on operating-bolt 9 of the same and adapted to makeContact with the under surface of the counterbore 4 to form an abutmentfor the operating-bolt, and with further rotation of the bolt in` arelease direction will cause in a positive manner the lower nut orexpander 7 to be forced downward out of its engagement vwith itscounterbore 5 to release the handle -bar stem from its engagement withthe fork-post. For the above'purpose 8o the collar 14 is located uponthe operatingbolt 9 a short distance below the upper screwthreadedportion thereof and is of a diameter somewhat larger than that of thelower end of the counterbore 4, as shown in Fig. 1.

l5 is a vertically-elongated slot formed, preferably, in the handle-barstem 3 near its lower end, and 16 is a projecting stud upon the lowernut or expander 7, that projects into said elongated slot to limit thevertical movement of said nut or expander. It is within the province ofthe present invention to reverse the arrangement of the said elongatedslot and stud, as well as to employ any wellknown equivalent means tolimit the vertical movement of the lower nut or expander 7.

With the present construction the two nuts l or expanders may be made ofcounterpart ta-I pering formation, as illustrated in the presentdrawings, or they may be made of a relative differential taper, as setforth in my aforesaid prior application.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination with the fork-post, of the handle-bar stem, havingtop and bottom slits and tapering counterbores, the handlebar formedwith a vertical bore that ts the upper end of the stem, tapering nuts orexpanders individual to the respective counterbores of the stem, and anoperating-bolt common to both nuts or expanders, substantially as setforth.

2. The combination with the fork-post, of the handle-bar stem, havingtop and bottom slits and tapering counterbores, the handlebar formedwith a vertical bore that iits the upper end ofthe stem, tapering nutsor eX- panders individual to the respective counterbores of the stem, anoperating-bolt common to both nuts or expanders, and provided with anenlarged collar and an abutment therefor formed within the interior ofthe handle-bar stem, substantially as set forth.

3.` The combination with the fork-post, of the handle-bar stem havingtop and bottom slits and tapering counterbores, the handlebar formedwith a vertical bore that Iits the upper end of the stem, tapering nutsor expanders individual to the respective counterbores of the stem, anoperating-bolt common to both nuts or expanders, and means forlimitingthe vertical movement of the lower nut or expander, substantially as setforth.

4. The combination with the fork-post, of the handle-bar stem having topand bottom slits and tapering counterbores, the handlebar formed with avertical bore that iits the upper end of the stem, tapering nuts or eX-panders individual to the respective counterbores of the stem, anoperating-bolt common to both nuts or expanders, and provided with anenlarged collar, an abutment therefor formed Within the interior of thehandle-bar stem, and means for limiting the vertical movement of thelower nut or expander, substantially as set forth.

5. The combination with the fork-post, of the handle-bar stem having topand bottom slits and tapering counterbores, the handleba'r formed with avertical bore that iits the upper end of the stem, tapering nuts orexpanders individual to the respective counterbores of the stem, anoperating-bolt common to both nuts or expanders and provided with anenlarged collar, and means for limiting the vertical movement of thelower nut or expander, the same comprising a verticallyelongated slot inthe handle-bar stem, and a stud on the lower nut engaging said slot,substantially as set forth.

In testimony whereof witness my hand this 2d day of November, 1898.

ANTHONY JEROME.
